winform中chart控件坐标放大问题

hello_dzm 2019-01-22 11:24:46

上面的图片是在我的项目里面,我放大后的结果,只有Y轴放大了,但是我没有找到错误,于是我单独写出来一个
这是程序:
foreach (var series in CHART_HisData.Series.ToArray())
{
series.Points.Clear();
}

string starttime = "2019-01-13 17:00:36";
string overtime = "2019-01-13 21:13:46";
MySqlConnection com = new MySqlConnection("server=localhost;port=3306;database=multiwaterinject;user=root;password=123456;SSlMode = none;");
string strcom = "select * from history where devId='" + 2 + "' and uploadTime between '" + starttime + "' and '" + overtime + "'";
MySqlCommand comand1 = new MySqlCommand(strcom, com);

try
{
com.Open();
//MessageBox.Show("查询成功！");
MySqlDataReader result1 = comand1.ExecuteReader();
while (result1.Read())
{
if (true)
{
CHART_HisData.Series[0].Points.AddXY(result1["uploadTime"], result1["inflowPressure"]);//来水压力
CHART_HisData.Series[1].Points.AddXY(result1["uploadTime"], result1["flowVolume"]);//累计流量
CHART_HisData.Series[2].Points.AddXY(result1["uploadTime"], result1["floodPressure"]);//注水压
CHART_HisData.Series[3].Points.AddXY(result1["uploadTime"], result1["flowSet"]);//设定流量
CHART_HisData.Series[4].Points.AddXY(result1["uploadTime"], result1["flowRate"]);//瞬时流量
CHART_HisData.Series[5].Points.AddXY(result1["uploadTime"], result1["floodOpenValue"]);//注水
CHART_HisData.Series[6].Points.AddXY(result1["uploadTime"], result1["drainOpenValue"]);//排水开度
}
}
result1.Close();
}
catch (Exception ex)
{
MessageBox.Show("Error：" + ex);//显示异常信息
}
finally
{
if (com.State == ConnectionState.Open)
{
com.Close();
}
}
下图是单独写出来的一个

两个代码是一样的
private void button1_Click(object sender, EventArgs e)
{
foreach (var series in chart1.Series.ToArray())
{
series.Points.Clear();
}

string starttime = "2019-01-13 17:00:36";
string overtime = "2019-01-13 21:13:46";
MySqlConnection com = new MySqlConnection("server=localhost;port=3306;database=multiwaterinject;user=root;password=123456;SSlMode = none;");
string strcom = "select * from history where devId='" + 2 + "' and uploadTime between '" + starttime + "' and '" + overtime + "'";
MySqlCommand comand1 = new MySqlCommand(strcom, com);

try
{
com.Open();
//MessageBox.Show("查询成功！");
MySqlDataReader result1 = comand1.ExecuteReader();
while (result1.Read())
{
if (true)
{
chart1.Series[0].Points.AddXY(result1["uploadTime"], result1["inflowPressure"]);//来水压力
chart1.Series[1].Points.AddXY(result1["uploadTime"], result1["flowVolume"]);//累计流量
chart1.Series[2].Points.AddXY(result1["uploadTime"], result1["floodPressure"]);//注水压
chart1.Series[3].Points.AddXY(result1["uploadTime"], result1["flowSet"]);//设定流量
chart1.Series[4].Points.AddXY(result1["uploadTime"], result1["flowRate"]);//瞬时流量
chart1.Series[5].Points.AddXY(result1["uploadTime"], result1["floodOpenValue"]);//注水
chart1.Series[6].Points.AddXY(result1["uploadTime"], result1["drainOpenValue"]);//排水开度
}
}
result1.Close();
}
catch (Exception ex)
{
MessageBox.Show("Error：" + ex);//显示异常信息
}
finally
{
if (com.State == ConnectionState.Open)
{
com.Close();
}
}

}

下面的是两个的designer

明明一模一样,但是就是x轴不放大,求大神解救
